you originally theorized it might be a cos limitation. you could very well be right. sometimes those kind of things make their way in and aren't exposed in the admin UI.
thats why i'm saying to try adding with a new account. if you create a new account, manage to add 5 signatures and then suddenly the add button is greyed out, then you know it's not an issue that applies to only users that existed pre upgrade.
additionally if you are able to add a signature to an existing account using cli tools, then you know that it's not a cos issue.
you could always do a zmprov gc <cos> | grep -i signature and see if theres any options there
i wasn't suggesting anything that was menat to supposed to be permanent solutions, but rather ideas that were to help you figure out what hte problem is. |
